Sequential Treatment of Iliopsoas Tendon Cysts Combined With Medial Hip Snapping by Hip Arthroscopy.

Abstract

Tendon cysts of the iliopsoas muscle cause pain and snapping of the hip. These cysts are close to the femoral nerve and blood vessels, and the risk of open surgery is high, with cyst recurrence occurring frequently. We describe a method of hip arthroscopy for the orderly excision of iliopsoas cysts. During the operation, the iliopsoas tendon is identified and released, the cyst is excised, and peritendinous osteophytes are formed successively. This technique is a minimally invasive, safe, and highly effective hip arthroscopy technique that addresses both intra- and extra-articular lesions.
